Brake lights come on when disconnected from truck

[Collier and Joan]

As soon as I disconnect from tow vehicle,  these 4 lights come on dimly lit on both sides of trailer.

That would be water in the plug. When wet inside power from wire that leads to battery shorts to wire going to the lights.

Hold the plug upside down and shake. Get used to storing it upside down too. A dielectric spray would not hurt. Long term could cause corrosion and hence a poor connection. ( I use WD40). We have found that the plug will fit between the frame and the plastic counts cover.

We used to hang it over the tounge in the winter too. Until one year soft fluffy snow built up and the wind caused my tailights to come on. it was a head scratcher at first, but the solution was easy...

A couple of additional comments… we found a rubber cover for the trailer 7-pin connector that keeps the water out if stored vertically. It MIGHT have come from eTrailer.com??

We also have a water resistant fabric cover over the head of the tongue jack, and sometimes slip the 7-pin connector up under that cover to keep it dry.

I got mine from Amazon for $10:

Like others, we got a cord holder that mounts to the front jack post.  It covers the openings when the plug is seated.  Then, we cover the whole thing with a heavy duty cover that goes over the top of the jack and extends down past the plug holder.  Keeps it nice a dry.  Mike

Mike, do you have a picture of that?  I haven't bought a front jack post cover yet.

John - 

HERE is a link to the replacement jack cover I recently bought.  There are a bunch of them out there to chose from.

Bill, do you put the pig tail up under that cover too?  I see some recommend putting a grease of some type on the plug to keep moisture out of it too.

JW - 

HERE is an example of the grease that is being talked about.  I use a Q-tip to get down into the 7 way plug (pigtail).  You don't want to gunk it up in there - just enough to put a very thin coating on the metal parts.

No, I don't have one of those "fancy things" like Mike & Carol, Rivernerd, etc..  I simply loop the pigtail behind the jack and make sure that it is hanging in a downward direction.

Bill

p.s.  One week to go!  Have a great time!

John, here are links to my “fancy” (as Bill says) cord holder and cover.

Cover

Jack Post Cord Storage

I don’t really have a clear picture of them on the trailer.  I mount the storage thing high enough on the post so that when the plug is in it the jack cover is over the entire thing.  It’s worked well and isn’t expensive.  Mike

We mounted it on our tongue box.
